  • Linux: Delete file & folder using command line terminal - Linux Shout

    As we know Linux is slightly different from Windows for various tasks even in deleting files and folders. And here we will see the quick Linux commands to delete a file and directory using the terminal.

    However, just like in Windows, system files or the important folders are only accessible by admin, in Linux, they are under sudo or root users. Therefore, if want to delete any system file on Linux using GUI, then you should log in as root but that is a bit risky because you don’t want to run all your applications under an admin user.

  • Automate setup and delivery for virtual machines in the cloud | Opensource.com

    If you're a developer or hobbyist using a Fedora qcow2 image for the cloud, you always have to do a bunch of initial configuration before an image is ready to use. I know this all too well, and I was eager to find a way to make the setup process simpler. As it happens, the entire Fedora quality assurance team feels the same way, so we developed Testcloud.

  • How to Run a Shell Script in Linux [Essentials Explained]

    Using #! /bin/bash indicates that the script is bash shell script and should be run with bash as interpreter irrespective of the shell which is being used on the system. If you are using zsh specific syntax, you can indicate that it is zsh script by adding #! /bin/zsh as the first line of the script.

  • Simple guide to secure Redis Installation - The Linux GURUS

    In our previous tutorial, we learned how we can install Redis on the Ubuntu server & CentOS/RHEL server. But if we leave the installed Redis service to default state i.e. with default configurations, it might be susceptible to intrusions. So we should know how we can secure the Redis installation to avoid unauthorized access or operations on our Redis server.

    There are a number of things we can do to secure the Redis installation. We will now list them down one by one.

  • Running syslog-ng in Bastille – revisited

    Bastille is a container management system for FreeBSD, similar to Docker or Podman on Linux. The historical name of containers on FreeBSD is jail, and they appeared a lot earlier than containers on Linux. Managing jails was not always easy. When I started to use this technology in production in 2001, nothing was automated. Using Bastille, you can easily create, configure, or update jails at scale. It has a template system to install applications in containers and there is a template also for syslog-ng.

    Need more of the classic FPS Quake in your life? Check out the newly released Torrent of Impurities by a bunch of Finnish mappers which serves up another dose to blast through. In development for over 9 months it brings over 7 new maps with thousands of monsters spread throughout. Plenty of secrets to find for this will too with over 120 to scout out and find.

  • The GoD Unit is a brain-tickling first-person physics puzzle game out now

    With the recent updates to Portal 2 I got a needy feeling for more first-person puzzle goodness and thankfully The GoD Unit seems to deliver on that. Note: key provided by the developer. The idea here is that you're going to be playing with mass. Using the tried and tested weighted cubes from Portal and other puzzle games, you run around rooms moving cubes around to press down buttons. However, there's quite a bit more than meets the eye here. You're constantly messing around with the mass of these cubes, making them weigh more or less using the special tech in the facility. [...] Cat Floor Studio, the developer, is a solo studio too which is surprising given how much thought went into this i would have expected at least 3-4 people on it. Always surprises me what tiny teams and solo developers can do.

  • Super charming 3D burrowing platformer Mail Mole is out now

    Love 3D platformers? Mail Mole from Talpa Games and Undercoders is out now with its sweet family friendly setting that sees you fire a mole around various different lands. Note: key provided by the developer. In Mail Mole, someone has sabotaged and hacked into all the power stations and so it's your job to burrow through all these magical lands to deliver a special password to each of them and bring them all back online. Not a particularly challenging game but still a wonderful addition to the 3D platformer genre, one that a younger audience will definitely enjoy a lot.

  • Perl weekly challenge 102
  • Perl is dead ... when I'm dead!

    Yes, I'm well on-trend, by a couple of months. As you see, lockdown has made a hot mess of my blogging schedule. I count myself very fortunate that is the worst effect it's had on me, alongside the gaining of some mass. WfH WARNING! Watch out for those caramel waffles! A single Stroopwaffle has enough calories to feed a hungry village for a day and are not a sustainable treatment for anxiety. Two kWh per packet, not a word of a lie.

  • Google released an exciting upgrade to a resource most people won’t even recognize

    When Google released Flutter a few years ago, I wondered whether Google was quietly laying the groundwork for Android’s demise. That’s because we already knew at the time that Google was quietly working on its next-gen operating system that would one day replace Android and Chrome OS. Called Fuchsia, the new OS would supposedly have many advantages over Android and Chrome, including a dynamic user interface that would adapt to any device, regardless of screen or interface. Fuchsia could power smartphones, tablets, laptops, and smart gadgets, or that’s what we’ve been hearing. But forcing the jump from Android to Fuchsia required another key piece of software, and that’s Flutter comes in. Fuchsia would have to run all of the apps available in Google Play, so users and developers could easily transition to a new operating system. Flutter is Google’s own development kit that allows developers to code an app once and then release it across platforms, whether it’s Android, iPhone, or desktop operating system. And Google just made a significant upgrade to Flutter, releasing version 2.0 that targets developers across all possible platforms.
